President Donald Trump approved a declaration of a state of emergency in California on Friday, ordering federal assistance in response to multiple wildfires that have broken out and continue to cause massive damage in the state since December 4.

A homeless man, Jesus Fabian Gonzalez, was arrested Sunday afternoon in Wine Country on suspicion of arson after leaving a creek bed where a fire was burning in Sonoma County’s Maxwell Farms Regional Park.

California has 64 active fires burning across the state, with the worst devastation caused by the seven major Wine Country fires, fueled by 68-mile-per-hour Diablo winds that have burned 94,000 acres, killed 11 people, and destroyed at least 2,000 homes and businesses.
